The brake controller wiring harness connector for the 2005 GMC Envoy is located under the dash on the driver's side of the vehicle. Look for a connector plug not connected to anything, next to the hood release latch.
A 2004 Envoy that makes a beeping sound when you start it could have a short in the electronics that control the seats. Take notice as to whether or not the seat moves a tiny bit when you hear the beep. If it does, it is the wiring.
Must be accessed through the door panels for ability to unplug wiring harness to mirror.
You need a 7 pin circular to 4 pin flat adapter. www.trailvoy.com
